我有一个使用高级自定义字段的中继器,当计数根据迭代计数达到总数(3)时,我想输出一个div,然后重置计数器。
这是代码,目前它没有按应有的方式输出,我对数学的了解不足以让它工作。
感谢您的帮助:-)
<?php if(have_rows('flexible_row')) : ?>
<div class="row">
<?php if(empty($count)){ $count=1;} while(have_rows('flexible_row')) : the_row(); ?>
<?php if(get_sub_field('column_width') == "One column") { $count = $count+1; ?>
<div class="col-sm-4">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
Count is <?php echo $count; ?>
<hr/>
</div>
<?php } if(get_sub_field('column_width') == "Two columns") { $count = $count+2; ?>
<div class="col-sm-8">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
Count is <?php echo $counter; ?>
<hr/>
</div>
<?php } else { $count = $count+3; ?>
<div class="col-sm-12">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
Count is <?php echo $counter; ?>
<hr/>
</div>
<?php } if ($count == 3) { ?></div><div class="row"><?php $count = 0; } ?>
<?php endwhile; ?>
</div>
<?php endif; ?>
认为我的逻辑有点混乱——我没有正确使用else
子句。这是最终的工作代码,以防将来有人偶然发现它:
<?php if(have_rows('flexible_row')) : ?>
<div class="row">
<?php if(empty($count)){ $count=0;} while(have_rows('flexible_row')) : the_row(); ?>
<?php if(get_sub_field('column_width') == "One Column") { $count = $count+1; ?>
<div class="col-sm-4">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
</div>
<?php } elseif(get_sub_field('column_width') == "Two Columns") { $count = $count+2; ?>
<div class="col-sm-8">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
</div>
<?php } else { $count = $count+3; ?>
<div class="col-sm-12">
<?php the_sub_field('title');?>
<?php the_sub_field('content');?>
</div>
<?php } if ($count == 3) { ?></div><div class="row"><?php $count = 0; } ?>
<?php endwhile; ?>
</div>
当然,您也可以使用switch
语句。
